Rikki, all of Garritans Libraries are good. They are not top of the line but they are a good compromise between very large samples and quality of sound. Garritan does fairly well with replicating real world accoustic instruments.

I plan on getting the GM Wavetable as soon as it becomes available. In the meantime, I will continue to use NI's Bandstand. Keep in mind, I only use these type of libraries for the auto accompaniment. For lead instruments (samples of accoustic instruments) I tend to use top of the line libraries with kontakt. It sounds so good and I have been at this for many years and plan on staying with the software approach.
